Geothermal heat pump air conditioning/refrigerating compound system

Abstract

The invention discloses a ground source heat pump air conditioning / combined refrigeration system, which consists of five subsystems, including a buried pipe heat exchanger system, heat pump air conditioning system, air conditioning terminal system, a cooling system and a heat medium circulation system. The buried pipe heat exchanger system is the major cold / heat source of the ground source heat pump air conditioning; the cooling system adopts the mode of water cooling, the exhaust heat of the cooling system is used as an auxiliary heat source all the year round for the ground source heat pump air conditioning with high heat load, thus a peculiar ground source heat pump air conditioning / combined refrigeration system is achieved, thereby meeting the demands of air conditioning users and cooling system users all the year round and ensuring the performance of the system for long term operation. The buried pipe heat exchanger system is connected with the heat pump air conditioning system and the cooling system via the pipeline of the heat medium circulation system; the heat pump air conditioning system is connected with the air conditioning terminal system via the pipeline of the heat medium circulation system; and the control of cold / heat transfer is controlled through the adjustment of the heat medium circulation system. The invention has high energy-saving performance, the costs are low and the operation is reliable.

Description

Technical field: [0001] The invention relates to a ground source heat pump air-conditioning / refrigeration composite system using a ground source heat pump as a cold and heat source, and belongs to the technical fields of building environment and equipment engineering and refrigeration engineering. Background technique: [0002] The ground source heat pump system is a high-efficiency energy-saving device that uses underground shallow geothermal resources (including groundwater, underground rock soil or surface water, etc.) to provide both heating and cooling. Among them, the buried pipe ground source heat pump system is less restricted by environmental conditions, so it is receiving more and more attention. It takes advantage of the relatively stable temperature of the underground soil, and on the basis of inputting a small amount of high-potential energy, exchanges heat and cold with the ground through the buried tube heat exchanger buried underground to realize cooling in s...

Problems solved by technology

In addition, these existing patents are all small devices, not large system devices, and none of them involve buried pipe heat exchangers

In the existing ground source heat pump technology, most of them are ground source heat pump air conditioning technology, or the technology that combines ground source and solar energy, and there is no joint application of ground source heat pump air conditioning technology and refrigeration system.
